ELECTRIC STOVE.

Patented. Feb. 17, 1914? Application filed November 12, 1913. Serial No. 800,628.

'To all whom it may concern:

Be it known that I, CLAnsxcr; S. STEWARD, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Electric Stoves; and I do hereby declare the following to be a full, clear, and exact description of the-invention, such as will enable others skilled in the art to which it ap'pertains to make and use the same, reference being. bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. 1

This invention relates to certain new and in electric stoves and it has .for its object, among others, the provision of a heating chamber 'disposed beneath .the stove and adapted for utilizing the waste heat from the heating units and which also serves to prevent the upward irush of cold air which would have a tendency to cool the units and render the same less effective.

The invention contemplates the use of either one or more heat units as may be desired. \Vhile I have showna stove of sub stantially rectangular form I and provided with three heat units, it is at once evident that the form and size as well as number of units employed may be varied without deillustrated in the which, with the numerals of reference marked thereon, form a part of this application and in which Figure 1 is a front view. Fig. 2 is a top Fig. 3 is a central section on line 3-3 of Fig.2, and Fig. leis a transverse section-on line H of Fig. 3.

Reference now being had to the details of the drawings by numeral, 1 designates the stove which is constructed, preferably, of

The invention is clearly sheet metal and consists of a compartment 2 arranged beneath the heat unit 3. The wires 4. by means of which the current is maintained through the heat units, are extended along the bottom of the chamber, thence upward along the upper portion of the chamher to the pointat which connection 18 had with the unit or units. Separating the wires at the bottom and end of the compartment is a partition wall 5. Doors 6, 6 are hinged at their lower edges to the edge of the false bottoms and, when turned upward, serve to close the compartment.

The heat units 3 are seated within suit able openings provided'in the top of the stove. These units I have shown as of circu-. lar form but it will at once be evident that they may be, if desired, rectangular or other form and mayvary in size to suit the requirements. A slight space 7 intervenes between the outer edges of each unit and the surrounding edges 'of the opening within .which each is seated, the object of this opening being to prevent the heat from the unit being imparted to the top of thelstove.

.In the present instance, I have shown the stove provided with that type of unit in which a series of resistance wires is provided within the upper face of a plate or disk of steatite or soapstone, the heat radiating from the resistance wires being per mitted to escape through open slots formed in the surface of the unit and being imparted to the plate upon either side of the slots. Suitable supports, such as legs 15, are provided and thecurrent thro'ugh'the heater is controlled. by means of a suitable switch 16 of ordinary construction. 7 v

The operation and advantages of the invention will, from the foregoing description, be readily understood, i

In the use of the stove, there must necessarily be a certain amount of waste heat within the spacebeneath-the heat units. The essential object of the present invention is to retain this heat for heating or warming purposes. The side walls and false bottom of the chamber 6 being imperforate, it will at once be noted that, when the doors of the compartments are closed, the heat I will be thus retained within the compartment and that the compartment will serve as a convenient receptacle for foods which it is desired, to keep warm or to be slowly cooked. It will also be-noted thatthe com partment form of the stove, the i stantially is shown and described.

ingfrom my invention which contemplates the use of a closed chamber disposed beneath the electric heating units of a'neleo tric cooker, the said chamber serving as a heat retainer forthe heat radiating from the lower portion of the heat unit-s.
